Footwear sole



FIG. 1 is a bottom plan view of footwear sole showing our new design; and,

FIG. 2 is a bottom plan view thereof showing an unclaimed surface pattern applied to the footwear.

The broken short dash-long dash line(s) defining the bounds of the claim form no part thereof. The broken lines shown in the drawings represent unclaimed environment and are for illustrative purposes only, forming no part of the claimed design. 

I claim the ornamental design for footwear sole, as shown and described.
